Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481984, here are decompositions:

101 + 481883 = 481984
137 + 481847 = 481984
197 + 481787 = 481984
233 + 481751 = 481984
263 + 481721 = 481984
311 + 481673 = 481984
317 + 481667 = 481984
641 + 481343 = 481984

Showing the first eight; more decompositions exist.
